Referring more particularly to Figure 4 it will be noted that the valve 22 is directly connected by means of a slotted bar or rod 24 having universal oint (not shown) when necessary and arranged in a suitable casing with the dial key member 25 so that a quarter turn by the dial key member 25 will operate the valve 22 in the samedirection: VJ hen this key 25 ism the positlon as shown in F igures 4-and 5 and: the plun 'erg38isin the in position as shown in dotted lines in Figure 4 the valve 23 is automatically set inthe position as shown in Figure 1, while the valve 22 will be in the position as indicated in dotted lines in Figi ure 1.

In other words the valve 23" will b e open through the conduit 26 to the enginemanifold and through the conduit 27 to'the vaporizing chamber 10, while it will beclosed to the conduit 28. The valve 22iat the same time will be open to the liquidufuelconduit 29 and to the liquid fuel container 30 "through the conduit or pipe 31, the valve being closed at vaporizer and choke eliminator.

Mounted on the slotted bar-24andjheld in place by a small key 34 fitted therein is'a disc 35 adapted to turn with the bar on the latter being operated-by the key 25. On this disc is fixed and insulateda switch part 36 wir eddimet to the engine battery so that when the disc 35 is revolved a quarter turn to the left, the switchpart- 36 engages with the switch part 37 fixed to the under side of the dash, (see Figure 6) and wired as at 16 to the terminal 15 of the vaporizing chamber 10, the grounding of the current being obtained. through the engine. the; circuit being now closed and the vaporizer in use. V

. Connected to the valve 23-is a plunger when this plunger is pulled out the device is adapted to be used as a gas saver. Ti lie-n the plunger 38 is in the in position the valve 23 is set or positioned as indicated in Figure 1 in firm lines and by dotted lines in Figure 4 to operate the deviceas a' vaporizer and choke eliminatonf By pulling out the plunger 38 the valve 23 is-set at the position indicated in full'line s in Figure 4 causing the device to beused as a gassaver." The plunger 38' is provided with a lug 39 whioh is adapted to engage with the: disc 35limiting the travel on the plunger-outwardly. On the outer end of the plunger-is provided 21 knob 40 to engage with the dial and thus limit the inward travel of the plunger. A notch 41 formed in the plunger 38 is designed to slidably engage withthe disc 35 y erate the valve 23 to the position as shown in Figure 1, the slot 41 will register with the v periphery of the disc 35 permitting the disc to be rotated through thekey 25,--see Figure6. a Vhen the plunger ispulled-out the device automatically becomes a gas saver. In other words the plunger; must .be in to-permit the key 25 to turn the disc. Furthermore the -key 25must be operated to turn thedisc back to cut out positionbefore it is'possible to pull out "the plunger. i 1 The heating element and adsorbent material such 'as asb-estos projects intojthe. vaporizing chamber 10 sufficiently far to allow a res'ervo'irifo'r}vaporized gas and air above and about the asbestos projections. The vaporized gas with the air drawn in through the valve 22 is then drawn through the valve 23 to "the engine manifold when the engine is rotated for starting. The upper capor plug 12' is boredto engage with two tubes valves. The tube 32 .is projecting downdly i the vaporizing chamber 10 a .suitable'distance as at 33 to insure that no liquid' fuel will be drawn through the'tube 27 into the manifold. Attachedto the tube 32 or screwed orinserted directly. into the cap 12in any well known manner, is a threeway valve 22,?Qwhich in the position illustrated in Figure 1 cuts oil? the liquid supply 29 butallows that held 'iinthe container 30 to fall into the va'porizing chamber 10. This container in .the' case of engines" fitted with vacuum 'tanks'is left open to the air, the liquid fuel finding its ownlevel and when allowed to drain into the vaporizing chamber doe s so by gravity andthen air is also drawn through mixing with the vaporized 'fu'el'and when. introduced into the engine manifold and mixed withmore air coming in free through the carburetorforms the ex plosive mixture. In the case of engines fitted with force feed systems a simple valve and float would be requiredin the container 30, The container 30 may be a tube of larger dimensions than the tube 32 or may be of any suitable size and construction, andthe amount of liquid fuel held therein "may be varied tosuit diflerently powered engines.

Coming now to the three-way valve 23 thiS'iS fixed to the tube 2'( or screwed or inserteddirectlyginto the cap 12 and'ccmmunicates withthe gas tube .26 to the engine manifold and also to the tube 28 which is 32an tl' 2701 theends of two male three-way messes open to the air 'and,'as illustrated, suitably bent. When turned as shown in F gure 1, the valve 23 provides a clear passageway for the vaporized mixture from the vaporizing Y but if found to be more suitable, this chain bar can be used-in a horizontal position as In this modified form liquid fuel and air would. be introduced indicated in Figure 8.

at one end, as at as whilst the vaporized fuel and air would be drawn from the other end 44:. The general principle, however, is practically the same as already described.

In usual practice the liquid supply pipe 29 would be connected at a point ust below the vacuum tank, whilst the vaporized mix ture, after passing through the device, would be drawn into the engine manifold entirely independently of the carburetor, except that additional air is drawn through the carburetor to form the explosive mixture, the choke having been eliminated.

The device as previously referred to is preferably operated from the dash by means of a simple lever and dial switch as follows 1-- In one positionwith the lever and disk as in Figure 6 with the plunger 38 in','the valves 22 and 23 will be in the position illustrated in Figure l, and in which the electrical circuit is closed and the device is in operation for starting the engine, the liquid fuel intake 29 being-closed and the passageway 31 from the container 30 being open and the passageway 27 communicating directly through valve 23 with the pipe 26 leading to the engine manifold, while the air intake 28 is closed and the plunger 38 being locked in the in position. On the lever 25 being turned to the normal or cut out position as in Figure 5 to break or open the electrical circuit the valve 22 automatically assumes the position indicated by dotted lines in Figure 1, restoring communication between the fuel supply pipe 29 and the container 30 and closing the conduit 32' to the vaporizing chamber at the same time leaving the valve 23 in the normal position as shown in Figure 1.

My device may be fastened in any suitable position, preferably under the hood, also it may be secured on the dash or on the motor. In ordinary practice it would be placed below the liquid fuel supply so that the container 30 would be fed by gravity but in cases l of necessity the device could'be used with force feed pumps and fitted with a simple valve-and floati The essentialffeature ofmy device. is that the vaporized'fuel mixture-is drawn into the 7 enginev entirely independent of the carburetor while the choke may beentirely eliminated and consequently as the possibility of drawing liquid fuel into. the engine is eliminated dilution of the lubricating oils Twillbe in a greatpart reducedl 'Furt-hei lBGl-QtllQIlQVlCB may be used as a gasisaver' by relieving the suction on thev liquid fuel v I jet'of the carburetorlthrough the admittance of air to; the manifold other than through the carburetor."-
